Exterior photograph of the Chamber of Commerce Building, also known as the Ross Building or Chamber Lofts, located in Denver, Colorado. As the headquarters for the Denver Chamber of Commerce from 1910 until 1950, the Neo-Classical Revival style building is important for its association with the development of Denver as the business hub of the Rocky Mountain states. Designed by the Denver architectural firm of Marean and Norton, the six-story, steel frame building's facade is faced with granite and terra cotta.
